The Samsung is one of may other possibility available today. The only problem are the CPU power, because they have to use a fanless version.
Anyway, with 800Mhz Cpu is possible run a lot of stuff and for only $800 they offer really a nice PC console! ( someone there spend much more money just for upgrade the keyboard for install a simple Mp3 player or Ram, CD kit, USB 1.0 kit...)
Buy one simple PC toy like the Samsung and then Install for FREE one of this distribution: http://64studio.com/ http://jacklab.net/jacklaborg/english/?JackLab_Audio_Distribution

then you can run the all Linux Audio application that you like and for FREE!

Of course is NOT available one audio-midi player like the Mediastation, because we have included the Elastique commercial license, available only in a professional audio tools.

I suggest you then to use the new Qtractor 1.2: http://qtractor.sourceforge.net/qtractor-index.html
because is full audio-midi editor with Mp3/ogg support integrated.
IF then you wil use it, qtractor is compatible session with Qranger and then we can share songs with Voice.
( just import one standard midifile and then record your voice OR many voice tracks and SAVE)
The new Qtractor 1.3 will have also the global audio-midi transpose and time scretch, where you can in realtime transpse the whole song in the root key chord desidered!

Slow slow I think you are starting understand that the future is based ONLY by the PC system, HD Streaming and not with the old dated embedded solution.
give a look here too: http://www.smproaudio.com/index.php?option=com_content&task=view&id=73
need just to wait the right time...
Qrange will be a new generation of Audio-midi arranger than no another brand can compete...
